Abstract

Procédé de détection d'une fraude documentaire comprenant : obtenir (50) une première image d'un premier document et une deuxième image d'un deuxième document ; déterminer dans la première et la deuxième image des régions contenant respectivement le premier et le deuxième document ; appliquer (53) une procédure de détection de zones sensibles à des fraudes documentaires dans les régions de la première image et de la deuxième image recalée sur la première image ; diviser (55) chaque zone sensible détectée en une pluralité de sous-parties ; calculer une mesure de dissimilarité entre des sous-parties correspondantes de la première et de la deuxième image recalée; déterminer si le premier document est identique au deuxième document à partir des mesures de dissimilarité et si le premier document est différent du deuxième document, déterminer un niveau de différence entre le premier et le deuxième document en fonction d'une valeur représentative d'une proportion de sous-parties différentes ; et, détecter une fraude lorsque le niveau de différence est inférieur à un seuil prédéterminé.A method of detecting document fraud comprising: obtaining (50) a first image of a first document and a second image of a second document; determining in the first and second image regions respectively containing the first and second document; applying (53) a procedure for detecting areas sensitive to documentary fraud in the regions of the first image and of the second image registered on the first image; dividing (55) each detected sensitive area into a plurality of sub-parts; calculating a measure of dissimilarity between corresponding sub-parts of the first and of the second registered image; determine if the first document is identical to the second document from the dissimilarity measurements and if the first document is different from the second document, determine a level of difference between the first and the second document based on a value representative of a proportion different sub-parts; and, detecting fraud when the level of difference is less than a predetermined threshold.
